7 Best Chocks For Travel Trailer Stability On Hills Nomads Swear By

That slight, unnerving lurch you feel after unhitching on a slope is a feeling every travel trailer owner knows. It’s the moment you question if those little plastic wedges are truly up to the task of holding several tons of your home-on-wheels. On hilly terrain, standard chocks aren’t just about preventing a roll-away disaster; they’re about creating a stable, solid foundation so you can live comfortably without constant rocking and swaying.

Securing Your Trailer: Chocks for Hilly Terrain

Parking on an incline introduces forces that a flat campsite never will. Gravity is constantly trying to pull your trailer downhill, putting immense, sustained pressure on your chocks and suspension. This isn’t just a safety issue—it’s a livability issue. A poorly chocked trailer on a hill will bounce and sway every time you walk, turn over in bed, or the wind blows.

The goal is to create a rock-solid triangle of force. You need chocks that don’t just block the tire, but grip the ground and the tire tread itself. For tandem axle trailers, you also need to stop the tires from moving in relation to each other, which is the primary source of that fore-and-aft rocking that can drive you crazy.

Forget those flimsy, hollow plastic chocks that came with your starter kit. They can slip on gravel, crack under pressure, and are simply not designed for the sustained load of a sloped site. True stability on a hill comes from a system: heavy-duty ground chocks to prevent rolling, combined with a between-the-wheels chock to eliminate suspension play.

BAL X-Chock: Ultimate Tandem Axle Security

The BAL X-Chock is the gold standard for a reason. It doesn’t work on the ground; instead, it fits between the tires of a tandem axle setup and expands outward. This action applies opposing force to both tires, effectively locking them together and preventing them from rolling forward or backward.

By locking the tires, the X-Chock removes the play in the suspension. This is the secret to eliminating the majority of trailer movement. You’ll be amazed at how much more solid your rig feels once these are tightened down. It’s the difference between feeling like you’re on a land-based boat and feeling like you’re in a small cabin.

A critical point many miss: X-Chocks are a stabilizing tool, not a primary safety chock. You must always place your regular ground chocks first, before you unhitch. Only after the trailer is securely chocked on the ground should you install the X-Chock. Trying to use it alone is a recipe for a dangerous slip.

Andersen Leveler: The All-in-One Chock System

The Andersen Leveler is one of the most brilliant RV innovations in years. It’s a curved plastic ramp you drive onto to level your trailer side-to-side, offering up to four inches of lift with millimeter precision. Once you’re level, you slide a corresponding wedge-shaped chock under the ramp, and the whole assembly locks into place.

The genius is in its dual function. The chock not only secures the leveler, but it also serves as an incredibly effective wheel chock. Because it cradles the tire and is wedged tightly against the ramp, the wheel has absolutely nowhere to go. It’s a faster, more precise way to level and chock one side of your trailer simultaneously.

However, it’s not a complete solution on its own, especially on a steep grade. While the Andersen system perfectly locks one side, the other side of your trailer still needs a traditional, high-quality chock. Think of the Andersen as the ultimate solution for one side, which you then supplement with a solid rubber or heavy-duty chock on the other for total peace of mind.

MaxxHaul Solid Rubber: Unbeatable Grip & Durability

When you need pure, unadulterated stopping power, nothing beats a block of solid rubber. The MaxxHaul chocks are heavy, dense, and built for abuse. Unlike hollow plastic, they won’t crush, crack, or slide easily. Their weight is a feature, not a bug—it helps them stay planted where you put them.

The magic is in the material. The high-density rubber has a natural grip that bites into asphalt, concrete, and even loose gravel in a way plastic simply can’t. They often feature a ribbed texture for even more traction against your tire tread. When you place one of these, you can feel the solid connection it makes between your rig and the ground.

These are your first line of defense. Before you unhitch, before you deploy stabilizers, a pair of these should be wedged firmly against the downhill side of your tires. While they don’t stop the fore-and-aft bounce like an X-Chock, they are the non-negotiable foundation of safety on any kind of slope.

Camco Super Wheel Chock: A Reliable, Simple Solution

Sometimes, you just need a tool that does its job reliably without any fuss. The yellow Camco Super Wheel Chock is that tool. It’s a significant step up from the cheap, flimsy chocks, made from a much more durable and UV-resistant polymer.

Its design is simple but effective. The ribbed construction and classic wedge shape provide a good hold on both the tire and the ground. They are lightweight, easy to store, and often come with a rope for easy removal without having to get on your hands and knees. For single-axle trailers or for use on the "uphill" side of a tandem axle, they are a perfectly adequate and affordable choice.

This is your workhorse chock. It’s the one you use in combination with more advanced systems. While a solid rubber chock offers more grip and an X-Chock provides more stability, the Camco is the dependable piece of gear that rounds out your safety system. Never rely on just one type of chock when parked on an incline.

Fastway ONEstep: Easiest Tandem Axle Chock to Use

The Fastway ONEstep addresses the one major complaint about X-Chocks: the need to kneel and crank a wrench. This clever device wedges between your tandem tires and locks them together, but it’s designed to be placed and secured entirely with your foot. You simply slide it into place and step down on the scissor-mechanism’s cable-locking arm.

This convenience is a game-changer for quick setups or for anyone with knee or back issues. It provides the same fundamental benefit as a traditional X-Chock—eliminating tire and suspension movement—but with a fraction of the effort. Removal is just as easy, with a simple pull on the release cable.

The ONEstep is perfect for nomads who value speed and ease of use without compromising on stability. It’s robustly built and gives you that same "locked-in" feeling as its manually-cranked cousins. For those who move frequently, the time and physical effort saved with the ONEstep really add up.

ROK BLOCK Chock: Innovative Design for Max Stability

The ROK BLOCK looks different from a standard chock because it is different. Instead of a simple wedge, it features a curved, concave design that is meant to hug the contour of your tire. This simple change has a huge impact on its effectiveness.

By increasing the surface area contact with the tire, the ROK BLOCK distributes the load more evenly. This makes it much harder for the tire to try and "climb" over the chock, which can happen with small, steep wedges on a significant incline. The design essentially cradles the wheel, using its own weight to create a more secure hold.

This is a smart evolution of the traditional chock. It’s lightweight, highly visible, and offers a noticeable improvement in holding power over basic wedge designs. For those who want the simplicity of a ground chock but with an extra layer of engineered security, the ROK BLOCK is a fantastic choice.

Ultra-Fab Super Grip: Heavy-Duty X-Chock Power

If the BAL X-Chock is the standard, the Ultra-Fab Super Grip Chock is the heavy-duty upgrade. It performs the same function—expanding between tandem tires to lock them in place—but it’s typically built with beefier steel and a more rugged construction. This is the chock for owners of larger, heavier fifth-wheels and travel trailers.

The "Super Grip" name comes from the louvered arms that press against the tire tread. These small ridges are designed to bite into the rubber, providing an even more secure lock and preventing any possibility of slipping, especially on wet tires. It’s a small detail that provides a lot of extra confidence.

For most travel trailers, the BAL is more than sufficient. But if you have a particularly heavy rig, or you simply believe in the "buy once, cry once" philosophy of over-engineering your safety systems, the Ultra-Fab offers an unmatched feeling of robust security. It’s pure, heavy-duty peace of mind.

Ultimately, securing your trailer on a hill isn’t about finding one magic product, but about building a smart, redundant system. Combine the brute-force grip of a solid ground chock with the motion-canceling power of a between-the-wheels stabilizer. This layered approach is what separates a worry-free stay from a week of constant, unnerving movement, letting you relax and enjoy the view you worked so hard to get to.
